ki'ipplication filed July 23,1904. Serial No. 217,809.

To .all '1r/71,0711, 'ft 771/04/ concern:

Beit known that l, Sonmsxi LOUIS BOND, a citizen of the United States, and a resident of Charleston, in the county of Charleston and State of South Carolina, have invented a new and improved Cotton-Pickerpf which the following is a full, clear, and exact description.

My invention relates to cotton-pickers; and its object is to produce a simple device of its class which is provided with improved means for picking the cotton and delivering the same into a receptacle. The device is expected to be pushed along by a plantation hand and can be completely controlled by one person.

The invention consists of the construction and combination of parts, to be more fully described hereinafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding' parts in all the figures.

Figure 1 is a side elevation of the machine. Fig. 2 is a plan. Fig. 3 is a plan of portions of the mechanism, the same being broken away, as will appear. This view is upon an enlarged scale. Fig. 4 is a vertical longitudinal section taken substantially on the line 4 4 of Fig. 3 passing through the axis of one of my picker-cylinders- In this view a table upon which the picker-cylinders are mounted is shown in side elevation. Fig. 5 is a vertical section taken substantially on the line 5 5 of Fig. 1, this view being taken upon an enlarged scale, as will appear. Fig. 6 is a transverse section taken substantially on the line (i (i of Fig. 4and passing through a pickercylinder. Fig. 7 is a perspective showing in detail one of the picker-teeth carried by the cylinders. Fig. 8 is a side elevation showing a modi lied construction of the picker-cylinders. Fig. i) isa longitudinal section taken substantially on the line 9 9 of Fig. 8, showing a portion of one end of a picker-cylinder and the manner of mounting the teeth therein. Fig. l0 is a perspective view illustrating more in detail the manner of mounting the teeth in the modified form of cylinder shown in Fig. 8. Fig. 11 is a vertical section taken Substantially on the line 11 1l of Fig. 1.

Referring more particularly to the parts, 1 I

a rear fork 4, which extends rearwardly and downwardly, carries a caster-wheel 5, as indicated. At the middle portion of the yoke 1 a bracket 6 is rotatively mounted by means of a downwardly-extending pintle 7. This bracket constitutes a fork, the arms 8 whereof extend upwardly and receive rotatively trunnions 9, which support therebetween an elongated table or board 10.

At a suitable point to the rear of the bracket 6 the table 10 is provided with an opening 11, and a similar opening 12 is formed at the forward portion of the table. Adjacent, respectively, to these openings rollers 13 are mounted, and over these rollers an endless belt 14 passes. This belt is adapted to be driven in a manner which will be described more fully hereinafter, so that its upper run moves rearwardly upon the table or platform. 1t is intended to deliver' the picked cotton to a suitable receptacle, such as a bag 15, which is supported upon the frame in any suitable manner just below the table. as indicated.

At the forward extremity of the table 10 and on the upper side thereof there are mounted a pairof picker-cylinders 16, the same having horizontal axes. of rotation disposed longitudinally with respect to the table. The

axes of rotation of these cylinders are parallel,

and the cylinders are disposed, respectively, at the sides of the belt 14, referred to above. In this construction (referring especially to Fig. 4) cach of the cylinders 16 comprises an outer shell 17 of cylindrical form, the outer extremity of which is closed by a head 18, constitutng a bevel gear-wheel, the purpose of which will appear hereinafter. Rear heads 19 are carried in the shells 17, and these heads are formed, preferably, with integral trunnions 20, which are rotatively mountedi n suitable bearings 21. These trunnions 20 are provided with central bores 22, which are in alinerrw with similar bores 23, which are forr ally with the shell and which pass through the outer-heads 18. ln the interior of theshell 17 there is mounted an adjusting-bar 24, which has a cylindrical body 25 and comprises eceentricallyplaced reduced extren'iities or shanks and QT, the former of which is ro tatively mounted in the bore QQ, while the latter passes througl'i the bore 23. Each of the shanks LIT is mounted Yin suitable bearings 28, which are similar to the bearings 21, already described; but these. bearings are equipped with set-screws 29, which are adapted to clamp the adjlisting-bars in any angular position, as will be readily understood.

Upon the body Q5 of the adjusting-bar 24 there is rotatively mounted a sleeve 30, and this sleeve is provided with fianges b1 at its extremities, which abut against the inner faces of the heads 18 and 19, as indicated. rlhese lianges ali'ord means for mounting longitudinally-disjjiosed t othshafts 3Q, having' shafts 33 passing through them longitudinally, as shown, for this purpose. ln the tooth-headers are mounted a plurality of short arms or teeth 34, and these teeth project, as shown most clearly in Fig. (i, in the corresponding openings 35, formed in the shell 17, as indicated. ',lhese openings are very much larger in diameter than the teeth, permitting considerable freedom of movement, as will be readily understood.

Arrangement is made for transmitting a uniform rotation between the two cylinders 16. For this purpose bevel gear-wheels 36 are provided, rigidly carried by the same arbor, rotatively mounted in a suitable bracket 37 at the forward end of the table, and these bevel-gears mesh, respectively,with the bevelgears 18. Obviously the cylinders will rotate in opposite directions.

In order to impart a rotary movement to the cylinders, one of them, preferably the one at the right, is threaded in the bore 22 thereof, facilitating' the attachment of a shaft 38,which shaft extends longitudinally of the table to'- ward its rear and is rotatively mounted near the rear of the table upon a suitable bracket 39. Beyond this bracket it carries rigidly a bevel gear-wheel 40, which meshes with a corresponding bevel gear-wheel 41.l the same bcing rigidly attached to a pinion 42, meshing with the main gear-wheel 43. This main gear-wluel 43 is adapted to be continuously rotated by the operator of the implement by means of a suitable crank 44. This main gear-wheel also affords means for continuously driving the belt 14. To this end the rearmost of the rollers 13 carries rigidly a pinion 45, which meshes with the forward side of tlie main gear-wheel, as shown most clearly in Fig. 1.

The cylinders 16, together with their contiguous parts, are completely inclosed in a casing or hood 46, which is provided on its sides with feed-openings 47, protected by cowls or vizors 48, formed above them, as

shown, the same inclina-ing upwardly and inwardly. Uniting with the rear side of this hood 46 there is a cover 49, the same having substantially the form in cross-section shown in Fig. 11 being' disposed longitudinally with respect to the table and attached to the upper face thereof so as to inclose the upper run of the belt 14.

The extremities of the teeth 34 are preferably provided with slits or recesses 56, the same lying iu planes at right angle-s to each other and passing through the axis of the teeth. These slits or recesses are intended to facilitate the separation of the lint.

1n the preferred form of the cylinders the teeth 34 are attached along a straight line, and the openings 35 in the shell are correspoiulingly placed.

1n Figs. 8 to l0 there is illustrated a modiiied construction for the cylinders in which the teeth 51 are attached in sets upon collars or rings 59., said rings being loosely mounted upon the body of the adjusting eccentric bar 24. There is preferably one tooth in connection with each collar, and in this form of the device the openings 53, formed in the shell, are preferably disposed along helical lilies, as indicated in Fig. 8. 1n other respects this modified form is identical with the preferred form.

The mode of operation of the-implement will now be described: It being understood that the ilnplement would be pushed along by its operator, the crank 44 will be continuously rotated in the forward direction. This would operate to rotate the cylinders 16, respectively, in the direction of the arrows adjacent to them in Fig. The eccentric adjusting-bar 2.4 having been previously adjusted into the desired position, the cotton would be introduced into the feed-openings 47 beneath the cowls 48 and would be carried upwardly by the revolving protruding teeth, which would operate to pick the same and advance the cotton into the interior of the hood 46. By reason of the eccentricity of the adjusting-bar the teeth would operate to advance and withdraw themselves in theopenings 35 as the cylinders rotated, and the adjustment would be suoli that the teeth would project a maximum amount on the outer faces and Lipper faces of the cylinders, withdrawing theinselves inwardly as they approached the inner and lower portion of their revolution. Upon this arrangement the teeth would operate to deposit the cotton upon the upper run of the endless belt 14. The upper run of the belt is moved rearwardly, as indicated by the arrow in Fig. 4. The mechanismv for moving this belt has been fully described above. Passing to the rear, the cotton carried by the belt is preci pitated through the opening 11 and falls into the receptacle 15, as will be readily understood. The set-screws 29 euablethe axis of IOO IIO
